My options would be Lake Michigan or head to the Gulf or the east or West Coastlines. Your thoughts on the best place for a beginner?
The tidal current in the SJ's is serious business. I am not sure that would be the best for a beginners training ground. You need to be spot on with the charts also as there are numerous areas with rock outcroppings. No such thing as a "soft grounding" in the SJ's, very hard around the edgesFrom a beginner:
But if I were to pick one of these spots, it would be the San Juans. The land masses of the Islands buffer the winds and wave heights of the Pacific, so it is rare to have to manage anything over 15 knots (though I do remember being out on the deck reefing the main in 24+ knots). The scenery is spectacular. You can alternate between harbors one night (with showers) and anchorages/moorings the next. As a beginner, you'll learn currents and tides in ways you won't on Lake Michigan; every day is a different docking or mooring/anchoring experience, and that's good experience.
Enjoy!
